' UNITED STATES PATENT orric MAURICE C. RYPINSKI, OF YONKERS, NEW YORK,ASSIGNOR TO C. BRANDES, INQ, OF NEW YORK, N. Y., A CORPORATION OF NEWYORK- TABLE TALKER.

Application filed March 13, 1924. Serial No. 699,090.

To all whom it may concern:

Be it known that I, MAURICE 0. Brian- SKI, a citizen of the UnitedStates, residing at Yonkers, in the county of \Vcstcheste-r and State ofNew York, have invented a certain new and useful Improvement in a TableT alker, of which the following is a specification.

My invention relates broadly to electromagnetic sound reproducers. andmore particularly to an instrument for reproducing radio concerts. musicand lectures, which I have termed the table talker.

An object of my invention is to provide a unit assembly for anelectromagnetic sound reprodueer wherein the acoustic horn is directlyconnected to the cap, through the agency of a ferrule screwed therein,which cap is screwed over the casing enclosing the eleetron'iagneticoperating mechanism in such manner that the entire'casing may be setvertically downward into a supporting base and lirmly clamped inposition.

Still. another object of my invention is to provide a construction ofelectromagnetic sound reproducer Easing provided with an annularshoulder and a substantial base member into which the casii'ig may beset vertically downwardly against an annular flange on-the extremity ofthe base and locked in position facilitatingunuiufacture of theinstrument.

()thcand further objects of my invention will be, understood fromthespecification hereinafter following by reference to the :u-companyincdrawings, in which:

Figure l is a perspective view showing the table talker of my invention;Fig. 2 is a diagrammatic view illustrating the unit as embly which llprovide enabling the table talker to be set vertically downward. into asupporting base; Fig. 23 is a plan view of the unit assembly illuslrated in'Fig. 2; and l ic's. 1 and 5 show a plan and :1V side eleval'ionpartialtv broken away indicating the unit assembly of the table talkerand its adaptability 'l'or vertically downward i'nounting in a basewhich may also contain associated apparatus such as a radio receiver 0amplifier.

My invention contemplates the unitary structure of the electromagneticsound reproducer. An annular flange is provided around the top of ascrew threaded aperture in the cap on the casin I provide a screwthreaded ferrule having a shoulder. and when this ferrule is screwedinto the cap this shoulder rigidly abuts the afore mentioned flange.The. ferrule serves as a support for the acoustic horn. The cap isprovided with a depending annular skirt with atlange face. at its lowerextremity. The structure as a whole may then be set verticallydownwardly in an es )ecially prepared basc having an annular flange faceat the top thereof surrounding a central aperture. The flange face ofthe cap may thus contact 7 ith the. flange face of the base forming arigid support.

Referring more particularly to the drawings, reference character 1indicates the cusing which houses the electromagnetic oper atingmechanism. A screw cap M is provided on the casing having an annulardepending skirt containing interior screw threads which engage withexterior screw threads on casing 1. The screw cap 14". is thickened inits central portion as represented by re fcrence character 16 and anannular flange 17 provided around a screw threaded aperture in thecenter of cap 14. .A ferrule 20 is screwed into the aperture in the cap1-1; and firmly seated against the. top surface of flange 17. Theferrule 20 serves as a seat and support for the acoustic born 22. A flatannular flange 18 formed on the lower extremity of the skirt 15 of thescrew cap 11-.

It will be. observed that this instrument is complete in ilscll. thecdcctrical terminals being shown at '19 and 21 connected by flexibleleads 22). The complete table talker may be. placed vertically downwardinto the base or base 31 as represented in Figs. 2 and 5.

llorctofore in the. art it has been the practice to support the horndirectly in a base of some kind and then insert a receiver unit beneaththe base in some position where sound might be directed into the born.This practice is entirely unsatisfactory for quantity productionand l.have developed the present unit to facilitate production and improve itsreproducing characteristics. The base 20 is circular in contour with aflat annular flange 25 at is upper extremity surrounding a centralaperture of such size that casing 1 wnl snugly fit therein. The

annular flange 18 on cap 14: makes flat con-- tact with the flat flange25 of the base giving substantial support. It will be observed i n w 1'reducer may bnoperzii'od from the onl'put c rcuit 0 an electron tubemnpliiier, 0r radio YOCCiVlHQ' m amplifying :i pn1'ntns may he nmuntnlthursin.
